Verify the calibrated power levels using the CLI command
dvb tx show
.
Example:
# dvb tx show
Satellite (DVB) TX Configuration
--------------------------------
Auto start : Disabled
Population ID : 2
IDU output power : -26 dBm
EIRP : 42.0 dBW
Default CW Frequency: 14.488000 GHz
AAL5 Encapsulation : VC MUX
DVB Transmitter Status
----------------------
State : Off
#
Leave the CW on for fine adjustment of the antenna, or turn it off using the CLI command
dvb tx cw off
.
6.3.3 Fine
adjustment of antenna pointing
If the CW from the power calibration routine is still on, it can be used for the antenna fine-adjustment as
well. Otherwise start CW transmission on the default CW frequency by issuing the CLI command
dvb
tx cw on.
Ask the control centre if they are measuring the expected power level for the CW. If not, it is likely that
the antenna pointing is not optimal. Fine-adjust the antenna pointing until the CW power level detected by
the control centre is within their requirements.
6.3.4 Fine
adjustment
of antenna polarisation
Ask the control centre if the measured level of the CW on the opposite polarisation is lower than their
requirement. If not, fine adjust the rotation angle of the Rx/Tx/Feed Assembly with respect to the feed
horn until the polarisation discrimination is within specified limits.
